Engine seems to run fine and I don't notice anything wrong with it when Im driving... do I need to replace my ignition coil or not? What else could be the issue? I don't want to waste money having someone replace my ignition coil if that won't fix my issue. I know my CV boot is cracked so could that be causing the problem?

Choose your car for a more accurate estimate

This code relates to an engine misfire and is not related in any way to your CV boot. The CV boot is a transmission/axle component. There are a number of things that can cause this code to register in the computer such as any of the following: a faulty spark plug or spark plug wire, a faulty coil pack, a faulty oxygen sensor, faulty fuel injectors, a bad catalytic converter or low fuel pressure. I would recommend having an expert technician, such as one from YourMechanic, diagnose your misfire to narrow down what may be causing the problem.
